I demonstrate a source of bias in the common implementation of the dyadic event history model as applied to policy diffusion. This bias tends to severely overstate the extent to which policy changes depend on explicit emulation of other states rather than on a state’s internal characteristics. This happens because the standard implementation conflates policy emulation and policy adoption: since...

This paper reviews the extent and nature of convergence of information services in the United Kingdom higher education sector. It traces the history of the process of convergence since the 1980s; considers the principal drivers behind it; outlines some of the implementation issues which have arisen; and evaluates its impact. Although drawing upon a fairly substantial published literature, and t...

â â â  â â â  nowadays, the world economies are rapidly moving towards being more knowledge-based economy (kbe) and supporting the force of knowledge as a vital component of economic growth. this recent acceleration in the transition to knowledge-based economy in the world, has affected regional economic performance. in this paper, we surveyed the regional convergence in knowledge-based economy...

in this paper, we design a new model of preconditioner for systems of linear equations. the convergence properties of the proposed methods have been analyzed and compared with the classical methods. numerical experiments of convection-diffusion equations show a good im- provement on the convergence, and show that the convergence rates of proposed methods are superior to the other modified itera...

S OLVING an optimal control problem using a digital computer implies discrete approximations. Since the 1960s, there have been well-documented [1–3] naïve applications of Pontryagin’s principle in the discrete domain. Although its incorrect applications continue to this day, the origin of the naïvete is quite understandable because one has a reasonable expectation of the validity of Pontryagin’...

In this paper, we study the concepts of Wijsman statistical convergence, Hausdorff statistical convergence and  Wijsman statistical Cauchy double sequences of sets and investigate the relationship between them.

Modification of Newtons method with higher-order convergence is presented. The modification of Newtons method is based on Frontinis three-order method. The new method requires two-step per iteration. Analysis of convergence demonstrates that the order of convergence is 6. Some numerical examples illustrate that the algorithm is more efficient and performs better than classical Newtons method and ...

based on a complete heyting algebra, we modify the definition oflattice-valued fuzzifying convergence space using fuzzy inclusionorder and construct in this way a cartesian-closed category, calledthe category of $l-$ordered fuzzifying convergence spaces, in whichthe category of $l-$fuzzifying topological spaces can be embedded.in addition, two new categories are introduced, which are called the...

In this paper, we investigate the convergence of a sequence of minimizing trajectories in infinite horizon optimization problems. The convergence is considered in the sense of ideals and their particular case called the statistical convergence. The optimality is defined as a total cost over the infinite horizon.
